• port <number> 套接字应连接到的端口。将传递给 socket.connect(port[, host][, connectListener])。

  ¥port <number> Port the socket should connect to. Will be passed to socket.connect(port[, host][, connectListener]).

• host <string> 套接字应连接到的主机。将传递给 socket.connect(port[, host][, connectListener])。默认值：'localhost'。

  ¥host <string> Host the socket should connect to. Will be passed to socket.connect(port[, host][, connectListener]). Default: 'localhost'.

• connectListener <Function> net.createConnection() 函数的公共参数，发起套接字上的 'connect' 事件的 "once" 监听器。将传递给 socket.connect(port[, host][, connectListener])。

  ¥connectListener <Function> Common parameter of the net.createConnection() functions, an "once" listener for the 'connect' event on the initiating socket. Will be passed to socket.connect(port[, host][, connectListener]).

• 返回：<net.Socket> 用于启动连接的新创建的套接字。

  ¥Returns: <net.Socket> The newly created socket used to start the connection.
